Slot: Overvoltage (Major, SYS 1V/SYS 1.1V/SYS 1.5V/SYS 3.3V/SYS 5V/SYS 12V/SYS 12V/SYS 12V_2)

Slot: Overvoltage (Major, SYS 1V/SYS 1.1V/SYS 1.5V/SYS 3.3V/SYS 5V/SYS 12V/SYS 12V/SYS 12V_2)

Description

Alarm message:

Voltage above upper major threshold

or

Mainboard voltage (arg1 V) at arg2 V detection point exceeds the overvoltage threshold (arg3 V).

This alarm is generated when the voltage of the idetection point higher than the major alarm upper threshold.

This alarm is generated by the following sensors:

  • SYS 1V
  • SYS 1.1V
  • SYS 1.5V
  • SYS 3.3V
  • SYS 5V
  • SYS 12V
  • SYS 12V_2

Attribute

Yes

Parameters

Name

Meaning

arg1

Current reading of the sensor.

arg2

Voltage detection point.

arg3

Alarm threshold.

Impact on the System

When devices work with a upper voltage, the component performance deteriorates, the device service life shortens, which causes system breakdown.

Possible Causes

The mainboard is faulty.

Procedure

  1. Power off the compute node and remove it from the chassis.

    You can power off the compute node using either of the following methods:
    • On the HMM CLI, run the smmset -l bladeN -d powerstate -v poweroff command.
    • On the HMM WebUI, choose PSUs & Fans > PSU Management > Power Control, and click the power control button to power off the compute node.

  2. Replace the mainboard. Then, check whether the alarm is cleared

    For details about how to replace the mainboard, see the server user guide.
    • If yes, no further action is required.
    • If no, go to 3.

  3. On the HMM WebUI, choose System Management > Information Collection, and collect logs.
  4. Contact Huawei technical support.
